A population has a mean of u=30 and a standard deviation of sd=5. a. If 5 points were added to every score in the population, what would be the new values for the mean and standard deviation? b. If every score in the population were multiplied by 3, what would be the new values for the mean and standard deviation?

Example 1: A researcher wishes to estimate the number of days it takes an automobile dealer to sell a Chevrolet Aveo. A sample of 50 cars had a mean time on the dealer's lot of 54 days. Assume the population standard deviation to be 6.0 days. Find the best point estimate of the population mean and the 95% confidence interval of the population mean.
8.4 Consider a population consisting of the following five values, which represent the number of DVD rentals during the academic year for each of five housemates: 8 14 16 10 11 a. Compute the mean of this population. b. Select a random sample of size 2 by writing the five numbers in this population on slips of paper, mixing them, and then selecting two. Compute the mean for your sample. c. Repeatedly select random samples of size 2, and compute the x value for each sample until you have the x values for 25 samples. d. Construct a density histogram using the 25 x values. Are most of the x values near the population mean? Do the x values differ a lot from sample to sample, or do they tend to be similar?
